The elephant in the room is that many of those fires are criminal and that the French government has arbitrated budget restrictions against investing in fire-fighting equipment, especially planes.
It so happens that the current fire near Bordeaux is roughy in the same area as the historic fire of 1949 in which 82 people died (and currently still smaller, hopefully it will stay that way) [1], as someone else already mentioned.
Wildfires in Fontainebleau are not new, either, even if this year's one it is historically large. First laws against fires in the in forest and obligation of inhabitants to help in case of fire date from the 14th century [2].
Yes warming trends do not help and increase risk (hence need to invest in equipment and prevention) but there is also fabricated drama and lack of perspective, which are unfortunately how everything is reported nowadays.
